New to the cold...Lipo Storage Safe Temperatures???

[Desert Rc]

So new to Utah and looking for best storage option in the cold. Dont really want as many lipos as I have on the inside. So I have a ammo box that stays out in the garage. My garage probably drops sometimes down to 30 degrees. Is this a safe temp for lipo storage??

I have probably 30 Lipos from 2s to 6s in this box.... is this just a fireball waiting to happen. All have adequate charge.

I keep my lipos in the fridge for storage. They are safe down to about -40F if memory serves. Past that they start to degrade.

Which part of Utah are you in? I'm just south of Provo.

I just keep all my lipos in a balsa wood box between the water heater and a propane tank. lol

Actually, they're in an ammo box in my office. No problems in six years. I have even shot fully charged lipos, and got nothing more than smoke from them.

I think the biggest concern is overcharging them or dead-shorting them. Keep them at 60% charge when not in use, and you shouldn't have any problems bringing them inside. If they're just sitting there in a box, they lose power until they die, from what I've seen.

My $.02 anyway on the matter

I would think storing them cold would be good since whatever chemical reaction that limits their life will run slower at cold temps.

Ditto. Been doing this since back in the days with regular batteries and still do.

yup, I always pop my extra AA (etc) batts in the fridge too for storage.
Just make sure yo warm them all up before using them! (charging or discharging)
